I made a little interface program to connect an IBM 3151 ASCII terminal from 1987 to IBM mainframes. The source code and a Windows binary are available on github: https://github.com/norbertkehrer/mainframe3151

If you are interested in the details, a video about it is here:

If you own this really interesting terminal, you might want to try it on a (real or emulated) mainframe instead of your 3270.
